COOLING DEVICE FOR COOLING THE BUNG-RINGS OF TRANSPORT-CASKS DURINGPITCHING.

Specification of Letters Patent.

Patented Aug. 22, 1911.

Application filed October 20, 1910. Serial No. 588,179.

T 0 all whom it may concern:

Be it known that I, HEINRICH JAnNIsorI, a subject of the German Emperor,and resident of Kaiserslautern, Palatinate, Germany, have inventedcertain new and useful Improvements in Cooling Devices for Cooling theBung-Rings of Transport-Gasks During Pitching, of which the following isa specification.

WVhen the pitch is removed from trans port casks and new pitch isintroduced therein by means of pitch injecting and pitching apparatusesthe pitch flowing back as well as hot gases,etc.,evol\"edmust escapefrom the cask between the pitch in eeting pipe (pitch nozzle) and thebung ring. Owing to this fact and owing to the heat radiating from thepitch introducing pipe (pitch nozzle) the bung rings are heated to sucha degree that often the wood of the bung stave is carbonized whereby thebung rings become loose. Now, the present invention does away with thisdrawback by inserting between the bung ring and the pitch injecting pipe(pitch nozzle) a cooling device comprising a cone cooled by circulatingcold water and adapted to receive the bung ring of the cask and tosupport the latter. The excess of pitch and the hot escaping gases areallowed to escape freely between the pitch injecting pipe (pitch nozzle)and the cooled cone of the cooling body without the bung ring beingheated.

In the accompanying drawing: Figure 1 is a vertical longitudinal sectionof my improved bung bushing cooler. Fig. 2 is a cross section throughthe cooling device.

The cooling device comprises inner and outer tapering housings b and 0.The ends of the housings b and a, are provided with inner abuttingextensions 0, so that when the inner housing is fitted within the outerhousing, the extensions, a space or chamber 6 will be provided. Theouter tapering housing is provided at one end with tubular extensions 0and a, which communicate with the chamber 6 and projecting from the endof the outer housing are extensions or supports A nozzle 0., is passedthrough the opening 0, in the inner housing, and at its inner end it. isprovided with a series 01 exit openings 0, while its outer end isprovided with a support It, which engages the ends of the extensions j,to position the nozzle when the invention is in use. The ends of theextensions are curved to form a seat for the rounded portion of thesupport 70, as clearly shown in Fig. 1.

In use, the cooling device is inserted in a hung hole, and a water (orair) supply pipe is attached to the tubular extension 6. The watercirculates in the chamber Z), and passes through the tubular extension0. The nozzle (z, is then inserted in the opening 0, of the coolingdevice, the support /afbeiug seated in the curved seats of theextensions j, to center the nozzle, with reference to the coolingdevice.

By this constructii'm, the bung rin A, is prevented from being heatedwhen the hot pitch is passing tin-(nigh the nozzle, or by the hot pitchor gases escaping through the opening 0.

I claim:

In a caslepitching device, the combination of an outer tapered housingprovided with hollow extensions to form inlet and outlet tubes,extensions protruding from the outer tapering housing, and an innertapering housing fitting within the outer tapering housing and formed atits upper and lower edges with outwardly projecting flanges which bearagainst the inner surface of the outer tapering housing to form a spacewith which the tubes communicate.

In testimony whereof I have hereunto set my hand in presence of twowitnesses.

HEINRICH JAENISCII.
